At the two minute mark, the title says "Senators tie the score," and while the clip shows a runner crossing the plate, it's a force play at first base and the defense leaving the field. The run wouldn't have scored.
Looking at
the box score and play by play, the score knotted up in the eighth when two scored on a single by Harris. My guess is that this clip is showing the double play that ended the ninth and sent the game into extras.
I can just imagine going to the local theatre days later and watching the news reels... what a different world!
